He clarified that despite the pause, the embassy in Nairobi continues to conduct interviews for applicants who had already been selected under the Diversity Visa programme.
The clarification comes amid growing concern among Kenyans following reports that some lottery winners were unable to proceed with the visa process.
Many applicants had expressed confusion over the status of the programme and the fate of their applications.
Flock explained that the pause affects the issuance of new visas but does not halt all aspects of the process, particularly for those who had already reached the interview stage.
He noted that the embassy remains committed to engaging applicants and processing cases as far as current guidelines allow, even as the broader programme remains suspended.
The Diversity Visa programme, commonly known as the Green Card Lottery, offers eligible applicants from various countries the opportunity to apply for permanent residency in the United States.
Each year, thousands of Kenyans apply for the programme, hoping to secure a chance to live and work in the U.S.
The latest developments have therefore drawn significant attention from prospective applicants and those already in the system.
Flock urged applicants to rely on official communication channels for accurate updates regarding the programme, cautioning against misinformation circulating online.
He emphasised the importance of checking the U.S. Embassy website for the latest guidance and any changes to the status of the programme.
While interviews continue, it remains unclear when the issuance of new visas will resume. Applicants who have already been interviewed are now waiting for further direction on the next steps.
The embassy did not provide a timeline for when the pause might be lifted but indicated that updates would be communicated as soon as they become available.
The situation has left many hopeful applicants in a state of uncertainty, particularly those who had successfully progressed through earlier stages of the process.
